Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a channel state information (CSI) window having a size that is based at least in part on a time unit associated with the configuration. The UE may receive CSI reference signals (CSI-RSs). The UE may generate a CSI report based at least in part on measurements of one or more CSI-RSs that are within the CSI window. The UE may transmit the CSI report. Numerous other aspects are described.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of wireless communication performed by a user equipment (UE), comprising:
 receiving a configuration for a channel state information (CSI) window having a size that is based at least in part on a time unit associated with the configuration;   receiving CSI reference signals (CSI-RSs);   generating a CSI report based at least in part on measurements of one or more CSI-RSs that are within the CSI window; and   transmitting the CSI report.   
     
     
         2 . The method of  claim 1 , wherein the time unit corresponds to one or integer multiples of a CSI-RS periodicity. 
     
     
         3 . The method of  claim 1 , wherein the time unit corresponds to one or integer multiples of a time interval between consecutive CSI-RS occasions. 
     
     
         4 . The method of  claim 1 , wherein the time unit is based at least in part on system frame numbers. 
     
     
         5 . The method of  claim 1 , wherein the time unit is based at least in part on an offset relative to a CSI-RS occasion location. 
     
     
         6 . The method of  claim 1 , wherein the configuration indicates a starting slot for the CSI window. 
     
     
         7 . The method of  claim 6 , wherein the starting slot is based at least in part on a system frame number. 
     
     
         8 . The method of  claim 6 , wherein the starting slot is based at least in part on an offset relative to a CSI reference resource slot or a reporting slot. 
     
     
         9 . The method of  claim 6 , wherein the starting slot is based at least in part on an offset relative to a triggering slot. 
     
     
         10 . The method of  claim 1 , wherein a first time unit of the CSI window is a time unit that includes a first CSI-RS occasion that is no earlier than a triggering slot. 
     
     
         11 . The method of  claim 1 , wherein a first time unit of the CSI window is a time unit that includes a triggering slot. 
     
     
         12 . The method of  claim 1 , wherein the configuration indicates the size of the CSI window. 
     
     
         13 . A method of wireless communication performed by a network entity, comprising:
 transmitting a configuration for a channel state information (CSI) window having a size that is based at least in part on a time unit associated with the configuration;   transmitting CSI reference signals (CSI-RSs); and   receiving a CSI report.   
     
     
         14 . The method of  claim 13 , wherein the time unit corresponds to one or integer multiples of a CSI-RS periodicity. 
     
     
         15 . The method of  claim 13 , wherein the time unit corresponds to one or integer multiples of a time interval between consecutive CSI-RS occasions. 
     
     
         16 . The method of  claim 13 , wherein the time unit is based at least in part on system frame numbers. 
     
     
         17 . The method of  claim 13 , wherein the time unit is based at least in part on an offset relative to a CSI-RS occasion location. 
     
     
         18 . The method of  claim 13 , wherein the configuration indicates a starting slot for the CSI window. 
     
     
         19 . A method of wireless communication performed by a user equipment (UE), comprising:
 determining that a channel state information (CSI) report is to be dropped if a CSI reference signal (CSI-RS) is unavailable or not received; and   refraining from transmitting a CSI report if a CSI-RS is unavailable or not received.   
     
     
         20 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report if the CSI-RS are unavailable or not received at a threshold quantity of CSI-RS occasions no later than a CSI reference resource. 
     
     
         21 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report after a bandwidth part change or a serving cell activation. 
     
     
         22 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report after an uplink slot conflict. 
     
     
         23 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report after receiving a CSI report reconfiguration or a discontinuous reception configuration. 
     
     
         24 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report after an activation of semi-persistent CSI. 
     
     
         25 . The method of  claim 19 , wherein refraining from transmitting the CSI report includes refraining from transmitting the CSI report after a specified quantity of CSI-RS occasions. 
     
     
         26 . A user equipment (UE) for wireless communication, comprising:
 a memory; and   one or more processors, coupled to the memory, configured to:
 receive a configuration for a channel state information (CSI) window having a size that is based at least in part on a time unit associated with the configuration; 
 receive CSI reference signals (CSI-RSs); 
 generate a CSI report based at least in part on measurements of one or more CSI-RSs that are within the CSI window; and 
 transmit the CSI report. 
   
     
     
         27 . The UE of  claim 26 , wherein the time unit corresponds to one or integer multiples of a CSI-RS periodicity. 
     
     
         28 . The UE of  claim 26 , wherein the time unit corresponds to one or integer multiples of a time interval between consecutive CSI-RS occasions.
